New Sabine Hossenfelder Video: “Physicists Say They Know How Cold Fusion Works”

Thanks to Frost for pointing out a new video on Sabine Hossenfedler’s YouTube channel titled “Physicists Say They Know how Cold Fusion Works”.

In the video, Sabine discusses a paper published in the open access online journal New Journal of Physics titled “Known mechanisms that increase nuclear fusion rates in the solid state” by F Metzler, C Hunt, P Hagelstein and N Galvanetto. Link is: https://iopscience.iop.org/article/10.1088/1367-2630/ad091c

Here is the abstract:

We investigate known mechanisms for enhancing nuclear fusion rates at ambient temperatures and pressures in solid-state environments. In deuterium fusion, on which the paper is focused, an enhancement of >40 orders of magnitude would be needed to achieve observable fusion. We find that different mechanisms for fusion rate enhancement are known across the domains of atomic physics, nuclear physics, and quantum dynamics. Cascading multiple such mechanisms could lead to an overall enhancement of 40 orders of magnitude or more. We present a roadmap with examples of how hypothesis-driven research could be conducted in—and across—each domain to probe the plausibility of technologically-relevant fusion in the solid state.

Sabine’s take is that this is a very hopeful development, and she hopes that cold fusion scientists will continue their research in this area because the stakes are so high: potentially an unlimited source of energy is available. She notes that the research is low-cost and can be done in laboratories (as opposed to the high cost of fusion research)
